I’m not going to go into the super depth but I will tell you the pros of mirrors and some cons that I have noticed whilst using a mirrorless system.

Let’s start with pros:

Weight, mirrorless cameras are much lighter than their bigger brothers (the DSLR) this goes without saying but if you’re planning to use it professional I feel mirrorless systems are kind of the wrong way to go. Professional lenses are big and bulky which pretty much neglects the whole idea about how mirrorless systems are light. Yes, they are lighter than DSLRs but you’re going to end up with an unbalanced camera system which will more than likely be front heavy due to some professional lenses (e.g. Sony FE 85mm F1.4 GM Lens which weighs 820 grams but the Sony A7RII weighs only 625 grams). Overtime and prolong use this could affect your wrist as it has with me in the past.

Electric View Finder (EVF), this is one of my favourite things about mirrorless systems, they all tend to have what’s called an EVF where tradition DSLRs have what’s called an Optical View Finder. The benefits of an EVF is that you can see the photos exactly how your camera sees it! It also shows you’re exposure in real time and yes with this you can pretty much see in the dark! EVFs tend to have much more detail as well compared to an OVF.

Rapid fire (shooting speed), shooting continuously is a bonus and I think this is due to mirrorless systems not having a flip mirror and because of this they’re able to shoot quicker.

Previewing images with the EVF, this should technically be in the EVF point but I feel it deserves its own pointer just because how awesome it is, you can preview your image inside the EVF. You’re probably thinking why is this so awesome but it helps previewing images in bright sunlight.

That’s pretty much all the pros which can be applied to all mirrorless systems, so let’s now talk about cons:

Battery life, that’s a nightmare, mirrorless systems use a lot more juice on a single battery. This is across all mirrorless systems though Fujifilm, Sony, Panasonic, etc. battery life just is yet good enough in my opinion (not even satisfactory). They all range around 300 shots per single charge where as DSLRs can go up to approx. 900 or more on a single charge.

Autofocus, this is a toss-up. I feel DSLRs have the advantage here but I’ve used some mirrorless systems which focus swiftly. Although there is one thing I did notice, when mirrorless systems autofocus (specifically the XT-2) and shoot it’s a little difficult to track moving subjects (this is because the EVF needs to switch off so the sensor can capture the image, you don’t get that with OVF (Optical View Finder) since its Optical and not Electronic and does not rely on sensor to project the image into a small screen.
